Thus, when thepassageway 22 is supplied with 55 water, water will also be supplied to the trap chamber Leading from the trap chamber 24 at the desii-ed water level is a vent pipe 25. This vent pipe 28 is carried into the discharge or drain pipe i? adjacent the lower end thercoi. and, it desired, this vent pipe 28 can be of an oval shape in cross-section, and the inner wall of the discharge or drain pipe il can be hollowed out to receive the saine. This will make a smooth inner drain pipe contour, so that foreign objects will not adhere to the pipe.

Also extending into the trap chamber 24 through the upper wall thereof is an inverted gooseneck pipe 2l. which forms a water seal or trap. The free end of the pipe 2l' extends slightly above the upper end of the vent pipe 26, and. if desired, a splash plate 28 can be arranged in front of the open end of the vent pipe, so that if undue disturbance is caused in the water of the chamber, the water will not have a tendency to unduly drain from the chamber through said pipe 2E.

In the form of my invention shown in Figures l to 5 inclusive, the usual or conventional type or" flush tank 2i is employed. and in accordance with my invention, I place in said tank at the desired point, a casing 29 for housing the electric motor 3S and the fan 3i. The casing 29 is provided with a removable cover 32 above the water line of the ush tank, so that entrance into the casing can be had when necessary or desirable.

To reduce noise and vibration, the casing is suspended in the flush tank by means of shock absorbing coil springs. Certain springs 32 can be disposed between the bottom of the casing 2S and the ilush tank, and certain springs 33 can be arranged between the front of the casing 29 and the front wall of the flush tank. Other springs 34 can be arranged between the rear wall or" the casing and the rear wall of the flush tank.

In order to further reduce noise and vibration, the fan and motor 3i) and 3i are arranged together as a unit, and this unit is then suspended in the casing by means of coil springs 35, as is clearly shown in Figures l and 2. The intake oi the fan 3i has connected thereto a suction pipe 3l, which leads into the toilet bowl and communicates with the chamber 22, so that when the fan is running. a suction will be created in the bowl through the openings I9 and the flush ring i8. The outlet of the fan is connected to a pipe 3S, which leads to the gooseneck El. The inlet and outlet pipes 3l' and 38 have incorporated in their lengths. at the desired points flexible couplings 39. These couplings prevent vibrations and noise from being transmitted from the motor and ian to the casing 29, and from the casing 29 to the flush tank and bowl. In order to insure the proper lling of the gooseneck with water to form the water seal. one branch thereof has formed therein a small opening 4G below the normal water level in said trap chamber 24.

The usual fiush tank pipe 4i can be provided with a water trap 42. which prevents the drawing of air through the pipe while the fan is in operation. Thus, all of the air is sucked from the bowl through the flush ring.

The circuit to the electric motor 3D can be closed in any preferred manner, and the current for operating the motor can be derived from the house circuit. In order to make the operation or the device automatic, I propose to close a switch to the motor 30 when the pressure is placed upon the seat 43 of the toilet bowl.

The seat 43 at its rear end is provided with hanger hinges 44, which are mounted upon hinge pins 45. These hinge pins are carried by brackets 46 slidably mounted on the top of the bowl. The brackets 46 are normally held in a raised position by expansion Coil springs 4'! placed about the brackets and confined between shoulders 48 on the brackets and the top of the bowl. One of the brackets 48 is employed as the Operating device for the switch, and, consequently, this bracket is guided in a sleeve or bearing 49 carried by the top of the bowl i5. The lower end of the sleeve 49 has firmly secured thereto an insulating housing 5B. Firmly secured to the lower wall of the insulating housing is an electric contact 5I and a companion Contact 52 is carried by, but insulated from the sliding bracket. The contacts 5| and 52 have electrically connected thereto current-conducting wires 53 and 54. These wires can be led through a conduit 55 disposed in the flush tank 2l, and the conduit, in turn, can lead into the casing 29 to the motor. This conduit can also be provided with a iiexible coupling 56, so that vibrations will not be transferred along the length of the pipe. Gbviously, at a desired point, electrical connections can be made with the electrical wires 53 and 54 with the wires of the house circuit.

In operation of my improved device, when pressure is placed upon the seat 43, the rod 46 carrying the contact 52 will be lowered, and this contact will be carried into engagement with the contact 5i, and the circuit will be automatically closed with the motor 30. The fan 3| will draw all objectionable odors from the bowl through the flush ring, and air containing the foul odors will be forced under pressure into the chamber 24. This pressure will blow the water out of the gooseneck 21, and the air containing the foul odors will be forced into the pipe 26, and thence into the drain pipe. As soon as the circuit is broken, the fan 3i will cease its operation, and, consequently, the pressure in the chamber 24 will be relieved. The Water seal will again be formed in the pipe 21 by owing into the pipe through the opening 40.

By this construction and' arrangement, a simple and inexpensive means is provided for carrying orf of vile odors Without any danger of foul gases leaking back into a room from the toilet bowl.

If preferred, an expansion spring 5l can be interposed between the contacts 5| and 52 to insure the normal operation thereof, and means is employed for insuring the proper insulation of the spring from the contacts.

In Figures l and 2, I have shown the fan and motor mounted in a casing within the flush tank. Some manufacturers may desire to form the ush tank, the bowl, and the compartment for the fan and motor, as well as the trap chamber, all in one piece.

In Figures 6 and 7, I have illustrated one convenient arrangement of this type. As shown in these two figures, the bowl and flush tank 60 and Si, at their point of juncture and at the rear face thereof, are provided with a compartment 62.

motor and ian unit is suspended in the compartment by the use of suitable coil springs 6B, which are disposed at the desired appropriate points. The intake pipe El for the fan communicates with the iiush chamber 60 of the bowl, so that a suction will be formed in said chamber and in the flush ring 68. This pipe 61 is formed relatively high so as to eliminate back pressure therein. The outlet B9 of the fan communicates with the trap chamber 10 through a gooseneck 1I. The chamber 10 is supplied with water from the flush chamber 60 through the medium of a pipe 12. The outlet from the compartment 'I0 includes a short length of pipe 13, which communicates with a second chamber 'lll formed in the bowl, and the said second chamber then communicates with the drain pipe i5 by a short length of tubing 16. This form of my invention operates the same as that form just previously described.

In Figures 8 to l0 inclusive, I have illustrated an arrangement whereby a compartment can be formed integral with a flush tank 80. As shown in the mentioned figures, the rear wall of the flush tank 8D can have built thereon an enclosing wall 3i, which wall, cooperating with the rear wall of the flush tank and the bottom wall of the flush tank, forms a compartment 82 for the motor 83 and the fan 84. The motor and fan unit is suspended in the compartment by springs 85, and the inlet and outlet of the fan is connected with the other parts of my ventilated toilet in the same manner as the two forms of my invention previously described.

In all instances, the inlet and outlet tubes and other pipes leading from the fan and motor have flexible couplings incorporated therein.

Changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new is:
